Try this, Set collision with all of V4 (I’m sure you have) Scale the item a tad Bigger (it will shrink back during the Drape) and use an Animated Drape frame 0 T pose frame 30 your end pose. That might help.

I’m having problems with this as well. I’m using Studio4.5, latest build, refreshed my download of Dynamic clothing 64bit and serial etc…
That at least gave me the controls I couldn’t see in Basic.

I’ve used this before in Studio3+ but getting nowhere with Trinity Leather Jacket. I also updated my install of the jacket.
The product listing says it fits Genesis. I’m using the genesis character in a basic guarded pose.
The legs work out well after drape but the arms and torso fail.
